Notes:
(1) The weighted average was derived by adding the three years of individual level data (1999-2001), multiplying the sums of each level by the assigned standard weights, i.e. 1=orange, 1.5=red, 2.0=purple, and calculating the average.
(2) States were not included if respective counties got a grade of B or higher.
